IS-54 DIGITAL CELLULAR MODEM IMPLEMENTATION ON THE TMS320C5XThe IS-54 U.S. digital cellular standard specified by the Telecomm Industry Association (TIA) uses a p/4-DQPSK modulation standard as the new modulation for U.S. digital cellular communication systems. This document focuses on the theory and implementation of a p/4-DQPSK modem on the TMS320C5x 16-bit fixed-point digital signal processor (DSP). A description of the modem scheme, modem theory, the modem implementation and performance results are provided. A code source is cited along with an extensive reference list.
